New CO2 setup - how are my numbers?

[maxthedog123]

Well, 48 hours since I setup my pressurized CO2 system, my pH has gone from 7.6 to 6.6. I think that's what you are pretty much shooting for, right? 1 point drop in pH is 30ppm.

I need to watch the night CO2 - I am running it 24/7.

Here's the wierd thing - I am running about 1bps and only using a powered diffuser from Red Sea. How 'bout that?

Which diffuser is it? Do you have a link? That's quite efficient if it is indeed 1bps. I haven't read of any reactor/diffuser that works that well.

There's no reason not to run it 24/7 as it makes it to where your plants don't have to wait for the correct CO2 level when the lights come on. The less fluctuation the better in my opinion.

It the diffuser that came with my Red Sea yeast system:

I was pretty surprised that it went to that level myself. But I guess the numbers don't lie.

sounds good.

Well, I set this up on Thursday afternoon. I am running CO2 24/7 in a tank with a KH of 4. So far the pH has been 6.6 (30ppm CO2) each morning at 8am, 6.6 at noon, ~6.8 (17ppm CO2) in the middle of the afternoon, and about 7.0 (12 ppm) at lights out around 9pm.

This was sort of what I expected as the day went on, but hey, I'm new to pressurized CO2. Does this seem OK?

That's yeast CO2 not pressurized btw. Pressurized consists of a CO2 cylinder and a regulator at bare minimum.

I'm pretty sure he has a cylinder and regulator, was just saying he is using the "powered diffuser" from the yeast system previously in use.

turn the co2 up a little.

 

[maxthedog123]

I guess that was the point of my post. My morning reading is 6.6 pH which is about 30ppm CO2. My concern was getting too high of a CO2 reading during the night. Do you think that I can turn it up a bit and still have the fish OK overnight?

 

[Mgamer20o0]

yes some people run it as high as 50ppm. just watch your fish for the first couple nights. they should be fine.
